preparation example Construction
[0032] In another specific embodiment of the present invention, the preparation method of the above-mentioned red sports track material is provided, including:
[0033] Mix red mud, iron tailings, fly ash, clay and water to obtain a mixture, extrude the mixture into plain embryos, calcinate at high temperature to form red ceramsite, and crush it into small pieces.
[0034] Wherein, each raw material is dried first; the dried red mud and iron tailings are ball-milled to a particle size of 50-150 mesh and then mixed with fly ash, clay and water;
[0035] The moisture content of the mixture is 20%-30% (w / w);
[0036] The grain size of the plain embryo is controlled at 15-30mm;
[0037] The high-temperature calcination conditions are: 1000-1150°C calcination treatment for 1-1.5h; by controlling the calcination temperature and time, the calcined ceramsite has good wear resistance, water absorption and mechanical properties.
[0038] The particle size of the crumbs is 1-5 mm; thus...
Embodiment 1
[0043] All raw materials were dried for 2 hours respectively, then 40 parts of red mud and 15 parts of iron tailings were mixed, 5 parts of fly ash and 20 parts of kaolin were mixed, and ball milled to 150 mesh with a ball mill respectively, sieved and added to a mixer to mix evenly, and water was added to contain water Stir at a rate of 25%, enter the extruder to extrude into a plain blank of 20mm, and then calcine at 1150°C for 1.5 hours after drying, add a crusher, and crush it into a red sports track granular material of 1mm-5mm, which belongs to porous ceramsite. No smell, high temperature resistance, cylinder compressive strength 3.1Mpa, when the water completely submerges the runway, the drainage time is 8 minutes, the friction coefficient is 1.2 (GB / T 3960-2016), good friction resistance can effectively prevent wet and slippery in rainy days.
Embodiment 2
[0045] All the raw materials were dried for 2 hours respectively, then 30 parts of red mud and 10 parts of iron tailings were mixed, 10 parts of fly ash and 30 parts of kaolin were mixed, and ball milled to 110 mesh with a ball mill respectively, sieved and added to a mixer to mix evenly, and water was added to contain water Stir at a rate of 30%, enter the extruder to extrude into a 15mm plain embryo, and calcine at 1050°C for 1.3 hours after drying, add a crusher, and crush it into a red sports track granular material of 1mm-5mm. The granular material belongs to porous ceramsite. Odor, high temperature resistance, cylinder compressive strength 2.7Mpa, when the water completely submerges the runway, the drainage time is 11 minutes, the friction coefficient is 1.45 (GB / T 3960-2016), good friction resistance can effectively prevent wet and slippery in rainy days.
